Proposing changes to your work with pull requests

Use a branch to isolate development work without affecting other branches in the repository. Each repository has one default branch, and can have multiple other branches. You can merge a branch into another branch using a pull request.

You can create or delete branches directly on GitHub.

Pull requests let you tell others about changes you've pushed to a branch in a repository on GitHub. Once a pull request is opened, you can discuss and review the potential changes with collaborators and add follow-up commits before your changes are merged into the base branch.

Pull requests display diffs to compare the changes you made in your topic branch against the base branch that you want to merge your changes into.

Create a pull request to propose and collaborate on changes to a repository. These changes are proposed in a branch, which ensures that the master branch only contains finished and approved work.

You can create a pull request to propose changes you've made to a fork of an upstream repository.

You can mark a draft pull request as ready for review.

After you create a pull request, you can ask a specific person to review the changes you've proposed. If you're an organization member, you can also request a specific team to review your changes.

After a pull request is opened, you can change the base branch to compare the changes in the pull request against a different branch.

You can commit changes on a pull request branch that was created from a fork of your repository with permission from the pull request creator.
